Wan 2.5 API for AI video with audio output

Wan 2.5 is an AI video model developed by Alibaba’s Tongyi Wanxiang team that turns text prompts or single images into short HD videos, with audio output supported on current routes. Wan 2.5 API via Evolink AI is an integration layer that exposes this model through one user-friendly API, so you can call Wan 2.5 from your apps, SaaS products, or creator tools without touching Alibaba Cloud directly. It is designed for developers, marketers, and social media creators who want reliable video generation as a service rather than managing low-level infrastructure.

Wan 2.5 API is best at short, story-like clips that fit social platforms and performance ads. You can use it to produce product explainers, scroll-stopping intros, motion posters, and quick story beats that pair visuals with sound. Many teams use Wan 2.5 as a way to test hooks and concepts before investing in full productions, generating multiple variants of the same idea and letting real engagement data decide which direction to scale.

Wan 2.5 API delivers a strong balance of video quality, cost, and speed for 5 or 10 second videos, while newer models such as Wan 2.6 push further into multi-shot storytelling and advanced narrative control. For many day-to-day social and UGC tasks, Wan 2.5 already provides enough realism and motion to feel native in feeds, at a friendlier price point than heavy cinematic models. That makes it a good fit as a workhorse model in your stack, especially when combined with higher-end options for premium shots.

Wan 2.5 API supports both text-to-video and image-to-video modes, which you can choose through a parameter in the Evolink AI endpoint. In text mode, you provide a prompt describing scene, style, and pacing, and the model generates a fresh clip from scratch, with audio output supported on current routes. In image mode, you upload a still frame, key visual, or character and let the video animate around it, preserving identity while adding camera moves and transitions.

Per current route docs, Wan 2.5 API clips use documented duration choices of 5 seconds or 10 seconds, which is ideal for hooks, transitions, and bite-sized stories on social. Resolution options commonly span 480p, 720p, and 1080p, depending on your chosen settings and plan. This keeps render times and costs manageable while still delivering visuals that look clean on modern phone screens and ad placements in vertical or square formats.

Wan 2.5 API is typically billed on a per-second basis through usage-based credits, with pricing aligned to roughly mid-market levels for HD video generation. This means shorter clips and lower resolutions use fewer credits, while longer or higher-resolution clips consume more, giving you control over budget and quality. The result is a pay-for-what-you-generate model that works well for experiments, campaigns, and SaaS workloads with changing demand.

Wan 2.5 itself is a paid AI video generator from Alibaba's Wan lineup, not a free model, but you can usually try it without committing to a long contract by signing up for Evolink AI and using introductory credits to generate your first Wan 2.5 image-to-video or text-to-video clips. For teams looking for the cheapest Wan 2.5 access, the practical path is to compare the per-second cost of Wan 2.5 on Evolink against the official DashScope rate and choose the route that fits your volume. Use the Wan 2.5 playground or preview to validate quality before scaling up, and only top up credits once you have confirmed Wan 2.5 fits your social, ad, or UGC workflow.

Alibaba open-sourced earlier Wan releases such as Wan 2.1, while Wan 2.5 is documented as an API-accessible model on Alibaba's DashScope and Model Studio. As of April 2026, we have not found an official Alibaba source confirming Wan 2.5 itself as open source, so for the most current status please check Alibaba's official announcements. To use Wan 2.5 today, you can call it via the Wan 2.5 API on Evolink AI without managing Alibaba Cloud infrastructure directly.

Wan 2.5 API via Evolink AI is designed with commercial use in mind, from performance ads to branded content and embedded SaaS features. As with any AI service, you should still review the latest terms from both Evolink AI and the underlying provider, check usage guidelines for your region and vertical, and put a simple internal review step in place before launching client campaigns or high-visibility assets.

You can call Wan 2.5 API from backend services, serverless functions, low-code tools, or even no-code automation platforms that support HTTP requests. A common pattern is to trigger video generation when new content is created, when a user submits a brief, or on a schedule for recurring campaigns. Evolink AI’s documentation includes example requests, response objects, and error patterns so your engineering time goes into product logic instead of debugging raw infrastructure.
